Abstract

um método para produzir um poliol com elevado teor de grupos hidroxila primária e um elevado peso molecular médio numérico, inclui a preparação de uma mistura que inclui um catalisador de cianeto metálico duplo e um poliol de poliéter com baixo peso molecular tendo um peso molecular médio numérico menor que 1.000 g/mol. o poliol de poliéter é derivado de óxido de propileno, óxido de etileno ou de óxido de butileno, ajustando-se a mistura para ter uma primeira temperatura, adicionando-se pelo menos uma substância selecionada dentre óxido de propileno, óxido de etileno e óxido de butileno à mistura na primeira temperatura, permitindo-se que a mistura reaja para formar uma mistura reagida, adicionando-se um catalisador de ácido de lewis à mistura reagida, ajustando-se a mistura de reação incluindo o segundo catalisador para ter uma segunda temperatura que é menor que a primeira temperatura, e adicionando-se pelo menos uma substância adicional selecionada dentre óxido de propileno, óxido de etileno e óxido de butileno à mistura reagida na segunda temperatura, de tal modo que um poliol resultante tendo um teor de grupos hidroxila primária de pelo menos 60% e um peso molecular médio numérico maior que 2.500 g/mol seja formado.One method for producing a high primary hydroxyl group polyol and a high numerical average molecular weight includes the preparation of a mixture comprising a double metal cyanide catalyst and a low molecular weight polyether polyol having a number average molecular weight. less than 1,000 g / mol. The polyether polyol is derived from propylene oxide, ethylene oxide or butylene oxide by adjusting the mixture to a first temperature by adding at least one substance selected from propylene oxide, ethylene oxide and butylene to the mixture at the first temperature, allowing the mixture to react to form a reacted mixture by adding a lewis acid catalyst to the reaction mixture, adjusting the reaction mixture including the second catalyst to have a second temperature which is lower than the first temperature, and by adding at least one additional substance selected from propylene oxide, ethylene oxide and butylene oxide to the reacted mixture at the second temperature such that a resulting polyol having a primary hydroxyl group content of at least 60% and a number average molecular weight greater than 2,500 g / mol is formed.
